LIMP HOME FUNCTION
1.LIMP HOME BY TESTER
If the PCM(ECM) detects the fault of the SMARTRA or transponder, the PCM(ECM) will allow limp home function of
the immobilizer. Limp home is only possible if the user password (4 digits) has been given to the PCM(ECM)
before. This password can be selected by the vehicle owner and is programmed at the service station.
The user password can be sent to the PCM(ECM) via the special tester menu.
Only if the PCM(ECM) is in status "learnt" and the user password status is "learnt" and the user password is
correct, the PCM(ECM) will be unlocked for a period of time (30 sec.). The engine can only be started during this
time. After the time has elapsed, engine start is not possible.
If the wrong user password is sent, the PCM(ECM) will reject the request of limp home for one hour. Disconnecting
the battery or any other action cannot reduce this time. After connecting the battery to the PCM(ECM), the timer
starts again for one hour.

2.LIMP HOME BY IGNITION KEY
The limp home can be activated also by the ignition key. The user password can be input to the PCM(ECM) by a
special sequence of ignition on/off.
Only if the PCM(ECM) is in status "learnt" and the user password status is "learnt" and the user password is
correct, the PCM(ECM) will be unlocked for a period of time (30 sec.). The engine can be started during this time.
After the time has elapsed, engine start is not possible. After a new password has been input, the timer (30 sec.)
will start again.
After ignition off, the PCM(ECM) is locked if the timer has elapsed 8 seconds. For the next start, the input of the
user password is requested again.

REPLACEMENT OF PCM(ECM) AND SMARTRA
In case of an inoperative PCM(ECM), the unit has to be replaced with a "virgin" or "neutral" PCM(ECM). All keys have
to be taught to the new PCM(ECM). Keys, which are not taught to the PCM(ECM), are invalid for the new PCM(ECM)
(Refer to key teaching procedure). The vehicle specific data have to be left unchanged due to the unique
programming of transponder.
In case of an inoperative SMARTRA, there is no special procedure required. A new SMARTRA device simply replaces
the old one. There are no transponder- related data stored in this device.

the old one. There are no transponder- related data stored in this device.1. Things to remember before replacing (PCM(ECM))
2.Things to remember before a replacement (Keys & Additional registration)
a.When there is only one key registered and you wish to register another key, you need to re- register the key
which was already registered.
b. When the key #1 is registered and master key #2 is not registered, Put the key #1 in the IG/ON or the
start position and remove it. The engine can be started with the unregistered key #2.
(Note that key #2 must be used within 10 seconds of removing key #1)
c. When the key #1 is registered and key #2 is not registered, put the unregistered master key #2 in the
IG/ON or the start position.
The engine cannot be started even with the registered key #1.
d. When you inspect the immobilizer system, refer to the above paragraphs 1, 2 and 3.
Always remember the 10 seconds zone.
e. If the pin code & password are entered incorrectly on three consecutive inputs, the system will be locked
for one hour.
f. Be cautious not to overlap the transponder areas.
g. Problems can occur at key registration or vehicle starting if the transponders should overlap.
NEUTRALIING OF PCM(ECM)

The PCM(ECM) can be set to the "neutral" status by a tester.
A valid ignition key is inserted and after ignition on is recorded, the PCM(ECM) requests the vehicle specific data from
the tester. The communication messages are described at "Neutral Mode" After successfully receiving the data, the
PCM(ECM) is neutralized.
The PCM(ECM) remains locked. Neither the limp home mode nor the "twice ignition on" function, is accepted by the
PCM(ECM).
The teaching of keys follows the procedure described for the virgin PCM(ECM). The vehicle specific data have to be
unchanged due to the unique programming of the transponder. If data should be changed, new keys with a virgin
transponder are requested.
This function is for neutralizing the PCM(ECM) and Key. Ex) when lost key, Neutralize the PCM(ECM) then teach
keys.
(Refer to the Things to do when Key & PIN Code the PCM(ECM) can be set to the "neutral" status by a scanner. A
valid ignition key is inserted and after ignition on is recorded, the PCM(ECM) requests the vehicle specific data from
the scanner. The communication messages are described at" Neutral Mode". After successfully receiving the data, the
PCM(ECM) is neutralized.
The PCM(ECM) remains locked. Neither the limp home mode nor the "twice ignition on" function is accepted by
PCM(ECM).
The teaching of keys follows the procedure described for virgin PCM(ECM). The vehicle specific data have to be
unchanged due to the unique programming of transponder. If data should be changed, new keys with virgin
transponder are requested.
a.Neutralizing setting condition
a. In case of PCM(ECM) status "Learnt" regardless of user password "Virgin or Learnt"
b. Input correct PIN code by scanner.
c. Neutralizing meaning .
: PIN code (6) & user password (4) deletion.
: Locking of PCM(ECM) (except key teaching permission)
